i think for the first question; an oligopoly
for the third i think its; d. people accept it in exchange for goods and services.
im not sure about the 2nd maybe b or d
Answer:
(a) Hypergeometric distribution
(b) 0.785384...
Step-by-step explanation:
(a) looking at the question, we see that 
, suppose Evans studied s key terms, this implies that he has not studied 100 - s key terms. Suppose 
if X = k, then k out of the s key terms he had studied appeared. But 10 - k out of 100 - s key terms he hasn't studied appeared. Thus X is an Hypergeometric distribution, X~HGeom(s, 100 - s, 10) with PMF:
Answer:
side AC is 5
Step-by-step explanation:
by using th pythagorean theorm you would square both sides add them together and the square root the sum to get you answer.
AB =3 BC=4
9+16=25
25 square root is 5
makeing AC=5
Step 1 you need to cross multiply
Then divide both sides by eight which will then give you this answer
K= 3/2
Answer:
14.4222
Step-by-step explanation:
Distance between two points = √(x₂ – x₁)² + (y₂ – y₁)²
Distance between two points = √(6 – -2)² + (-5 – 7)²
√(6 – -2)² + (-5 – 7)²
√8² + (-12)²
√64 + 144
√208
14.4222
I hope this helps
